To all whom it may concern/: Be it known that I, ROBERT E. BoLn, aci'tizen offthe United States, residin at the city of Bakersiield, in the county of ern and the State of California, have invented anew and useful Pump for Oil-Wells, of which the following is a specication.

My invention relates to a pump and has speclal reference to such a pumnlas is usedin t eil pumping of oil and other 'ke Ar'tesian we s.

Heretofore the working barrel of vthe lordinary oilwell pump has been simply bored out 'as true as a lathe or boring-mill would ermitandthe plunger has been tted with eather, canvas, or other vcu s which would conform to any unevenness 1n the barrel or ump, and where a well was clean and Jree from sand or grit such a device has been in satisfactory use and has answered in the usual or ordinary cases. It has been found, though, in many .localities where oil is found'in loose or open sands that the above-mentioned device was inadequate and utterly useless on account of such sand coming in with the oil and other methods have been called for, the most efficient of which has been a barrel or pump of ordinary length and a .wrought or steel'pipe-plunr of about' the same length as the barrel, w 'ch plunger is turned and tted closely and of such a perfect fit in the barrel that it is without the slightest vibration and being shoved'from end to end without sticking or becoming clogged. Such a perfect Aiitwill thus prevent the sand or grit AJfrom getting between the barrel or pump and plungler, and so long as'it can be kept 1n this contion it will prevent the vbarrel or pum and plungerrom wearing out and the We l will pump untilsaid barrel or pump` and plunger are worn out and beme unfit for use. Such a. device has, however, been found to be much trouble in getting these.

barrels or pumps bored out perfectly true and straight, for s ould the bar for boring out these barrels or pumps spring out or 'a hard or soft lace in barrel or pump develop it would a low the bar to spring away from or dig into this hard or soft place, thereby making an unevenness opposite to it, and the plunger when turned to iit the barrel would ave to be turned to iit into the smallest part of said barrel, which would leave the plunger to it only at the said tight place or point, so-

that when it is put into the well and in pumping itwill allow the sand and 't to get lbetween the plunger and linin 'oltlhe barrel or pump, fthereby grinding le plunger and pum out very rapidly, as such sand and grit acts 'ke emery and will in many cases wear out a pump in less than a day, although in other and unusual cases where an almost perfeet fit was secured from end to end of barrel the punger and pum have lasted for many wee in the same'well). l

In order to secure a perfectly-slitting barrel or plunger at all times and secure a perfect fit from en'd to end of the same, and thus prevent the sand pumped with the oil from'getting in between the barrel and plunger of the pump, isvwhat my improved pump is designed tor, and it consists in borin out a number of sectional rings of about a oot in Ilength so that they are perfectly true on their inner faces and also turning er facing each end of said sections so that they are perfectly true at this part. The plunger is turned to a perfeet fit-for thesey sections of rings, and a cage formed of a casing or pipe is rovided O a pro er length and of. a size s cientlylarge to a low the inserting or pourin of a molten liquid or other suitable materialin the s ace between the rings and casing, which come set and hard within said space whenl material is placed between said rin s and casing, and thus said rings are quie y and securely held in place in order to secure a perfectly-true um and a perfect iit from end to endv thereof? and) becomes worn out thefhardening l material can be heated, so as to melt out and new sectional rings inserted and run up again in like manner from time vto time.

Therefore to enable those skilled in they art to `which my invention appertains to construct and use vmyimproved pump', l will dewhen at any time the pump scribe the same more fully, referring to the accompanyingdrawings, in which- Figure 1 is a longitudinal 'central section of my improved pump in its completed form and ready for operation. Fig. 2 is a crosse section of the same on theline -2 2, Fig. 1.

Eig. 3 is a perspective view of oneof the sectional rings.

ige. 4 and 5 are' views showing the mannerof inserting and removing the filling material in forming the ump.

Like symbols of reference erein indicate like parts in each of the figures of the drawings. v

As illustrated in the drawings, 1 represents the outer pipe or casing, which is provided with areducing-collar2 at its upper and lower ends and into which said-casing is screwed in the ordinary manner, while into the opposite ends` of these collars the usual tubing 1 is also secured in the usual manner. Within this casing 1 is the plunger 3, which is cylindrical in cross-section and preferably formed of steel tube or pipe, which plunger has its outer face turned and is of the same character and material and does its work in the same manner as the plungers in thisclass of work now-` in use. At the upper end of this plunger 3"l is the upper valve 4, which is secured thereto in the usual manner, and the lower end of the plunger is provided with a bushing or nut 5, having an opening 5 in the lower end of the same, through which the drawing rod or stem 6 passes, and is provided with the head 6 at its upper end for the purpose of withdrawing the standing valve 7 at its lower end from the well when the plunger is taken out of the well, while said lower or standing valve 7 is held stationary when in o ration within a valve-seat 7 secured at t e lower end of the casing 1.-

Within the casing 1 and fitting perfectly aroimd the plunger 3 is the lining 8, which is formed of a series of sectional rings 9 and referably of cast metal of about one foot in en th and smoothly faced or surfaced at eac of their ends 9', and such rings are also bored out on their inner faces 9 in order to forni a perfect fit around said plunger.

When my improved pump is to be formed, the casing 1 is held within a recess or seat a of a block A, resting upon the ground orfloor,

and the plunger 3 is run down said casing and onto a head a in the center of said block. ifter this is done the liners 9 are placed around said plunger 3 and above each other, with the lower one resting in the seat a/ of said block, so that an annular space 10 is formed between the casing 1 and said liners. The

liners 9' will form a perfect and smooth conneetion with each other in forming the lining 31 by their abutting ends 9 when in position, and the plunger 3 willform a perfect fit an'd connection with the inner faces 9 of said liner, so that a filling 11, of Babbitt or other molten 'metal or other metal or material, can be inserted, packed, or poured into the space 10 through the open upper end 10 thereof to form what is known as a complete working barrel, and thus making said liners or rings 9 forming said Vlining absolutely stationary and immovable in a true and correct position. rThe' plunger 3 can now be removed, and the other parts ready for use are removed from the block A, so that the collars 2 can be placed around the casing 1 and connected to the tubing 1 within the well, after which the plunger can be inserted within the lining 8 and operated in the usual manner in Working the pump. ln case the plunger 3 and lining 8 become worn out through the operations of said plunger within the same the rings 9 forming such lining can be removed by sim ply lifting out the plunger and disconnecting the lcollars 2 from the casing 1 and tubing 1', so that they pump can be removed and set` upon and around a cone-shaped portion b in a pan B to allow a flame from any suitable-source to pass up through an opening b in said cone and into the lining 8, thereby heating the parts to a sullicient deee, which will allow the metal or material forming the filling 11 to run out of the space 10 between the casing and lining, through the open lower end 10 of Said space, and in to the an and around said cone. The liners 9, forming the lining 8, can then beremoved and new rings or liners inserted around the plunger and within the casing, after which the space 10 can again be filled up by molten metal or material, as before described, to form another filling Within said space and a neW in the well.

It will be obvious that plaster-of-paris or any material can be inserted in the space between the lining and casing as a filling, and such material can be removed therefrom when desired by hammering the casing or by other means as desired in order to take out the lining when the same has become worn or for any other purpose.

It will thus be seen that my improved pump can be constructed easily, cheaply, and when in use will be found efficient for the purposes intended. The lining will be absolutely true and correct when in position and being true and free from friction with the plunger working within the same will not interfere with the operations of said plunger and will therefore add length of life to the pump. The pump can be finished in a shorter space of time than those ordinarily used, and it requires no skill or certainty in getting a perfect and true working barrel. The cost of production of the fluid to be pumped is greatly lessened, and when the pump wears and needs repairing all of the pump can be utilized at all times with the exception of the Wornparts. It will also be seen that my improved pump will do away with any bands, collars, or any vconnections around or between the ends of What I claim as my invention, and desire to secure by Letters Patent, is

1. In apump, the combination with a pluriger, of a cylinder which consists of an outer casing7 a series of lining-sections in said casing fitted to each other and to the exterior of the plunger but having'external dimensions such as to leave a space betweenthem and the outer casing, the parts being constructed to permit iiuid to loW into and out of said space, and a lling of fusible material which when molten, can be introduced into or allowed to run from-said space. 2. In a pump-cylinder7 the combination with an outer casing, oi a series of lining-sections therein fitted endwise to each other and adapted to it. the plunger but having external dimensions such as to leave a space between them and theouter easing, the parts being constructed to permit iiuid to flow intov or out of said space, and a filling of fusible material 'which When-molten can be introduced into or allowed to runirom said space. In testimony whereof I have signed ny J. R. WILLIAMS, BEDELL SMITH.
